Patent EP-3858731-A1 (EP)
Inventor: CHEN PENG
IPC: B64C27/48
Filed: 2019-04-18
Abstract: The present invention provides a propeller, a power assembly and an aerial vehicle. The propeller includes a propeller hub and at least two propeller blades arranged at equal intervals along a periphery of the propeller hub. The propeller blades are rotatably connected to the propeller hub through a rotating shaft so as to fold the propeller blades toward an axis of rotation of the propeller hub, or to unfold the propeller blades away from the axis of rotation of the propeller hub. In addition, there is a preset angle between an axis of the rotating shaft and the axis of rotation. The propeller hub is configured to be in connection with a drive device for power transmission, to drive the propeller hub to rotate around the axis of rotation. After the aerial vehicle lands on the ground, the propeller blades rotates around the rotating shaft, so that the propeller blades fold toward the axis of rotation of the propeller hub, thereby preventing the propeller blade from hitting the ground or an object on the ground, and preventing the propeller blade from being damaged.
